Sat Sep 21 16:12:33.403 JavaScript execution failed: SyntaxError: Unexpected identifier 

How can we restore or put data into mongoDB?? Please give me the steps.

Answer 1

mongodump: To dump all the records:

mongodump --db databasename 

---

To limit the amount of data included in the database dump, you can specify --db and --collection as options to mongodump. For example:

mongodump --collection myCollection --db test 

This operation creates a dump of the collection named myCollection from the database 'test' in a dump/ subdirectory of the current working directory. NOTE: mongodump overwrites output files if they exist in the backup data folder.

---

mongorestore: To restore all data to the original database:

1) mongorestore --verbose \path\dump 

or restore to a new database:

2) mongorestore --db databasename --verbose \path\dump\<dumpfolder> 

Note: Both requires mongod instances.

Answer 2

Dump DB by mongodump

mongodump --host <database-host> -d <database-name> --port <database-port> --out directory 

Restore DB by mongorestore

With Index Restore

mongorestore --host <database-host> -d <database-name> --port <database-port> foldername 

Without Index Restore

mongorestore --noIndexRestore --host <database-host> -d <database-name> --port <database-port> foldername 

Import Single Collection from CSV [1st Column will be treat as Col/Key Name]

mongoimport --db <database-name> --port <database-port> --collection <collection-name> --type csv --headerline --file /path/to/myfile.csv 

Import Single Collection from JSON

mongoimport --db <database-name> --port <database-port> --collection <collection-name> --file input.json
